Remember the 4:1 rule; The strength of the rope will be diminished when a bend in the rope is less than 4 times the diameter. Thus, most knots bend the rope at least less than this ideal formula. This is why strength degradation is applied when a knot is tied in any rescue rope.
Also known as
Full carrick Bend, Sailor's Knot and Anchor Bend. Beware! There are not many
knots with so much wrong drawings as this bend. The ends have to be on opposite
sites and the crossings always are alternating up/down/up/down... The Carrick
Bend is one of the best knots. Ashley states it is possible the nearest thing we
have to a perfect bend. It does not easily slip, not even if the rope is wet.
And it is always easy to untie, also after a heavy load. If used as a Hawser
bend in heavy material it is always seized and parceled to save wear.
The Josephine Knot
In the Macrame this knot is called the Josephine Knot. It is self evident the Josephine knot is not seized nor pulled tight.
The chief value of the Becket bend is its use in binding together two lines of different sizes. If there is a great difference in sizes or the strain on the line is to be great, always use a double Becket bend. To fashion a single Becket bend, you should make a bight in one line and run the bitter end of the other line up through it, as shown. Pass the end around behind both parts of the bight and back under itself. How you make a double Becket bend by simply taking another turn around the bight. (These bends are also known as sheet bends.)
Strength: 55% (normal), 40% (abnormal)
This knot does have a tendency to loosen and can come undone
so it is a good idea to used a half hitch to secure the "tail" of the
knot to the loop. Strength: 50% (normal)
A good knot for belays or for tying rub points out of a rope.
Its main advantage is that the two strands of rope emerging from the knot are at
180 degrees to one another rather than emerging in the same direction as in a
figure-of-eight for example. This makes it a good mid-rope knot and good for
belays because it has greater strength than a figure-of-eight if the belay
This one is worth learning for all those occasions when you forget your Stitch
plate or descender.
This simple knot is very useful for when you need a rapid belay around an object or though a krab.
The two knots that compose the double fisherman's should not be mirror images
of one another (i.e. they should have the same "handedness") otherwise
they won't stack properly.
This knot is excellent for tying in the middle of a climbing rope, for lashings of many kinds -- anyplace a loop that leads fair both ways in wanted. The method for putting it in is simplicity itself:
Take three turns of the rope round your hand, then:
1. Move center part (b) over right part.
2. Move new center part (c) over left part.
3. Move new center part (a) over right part.
4. Pull new center part (b) up to form the loop
5. For most satisfying results, remove hand before fairing or loading knot."
This knot is tied so that the load bearing tape emerges from opposite sides
of the knot so it will sit naturally when the sling is in use.
